Tom Coughlin has agreed to a contract extension through 2012, the Giants announced today. His deal was set to expire at the end of this season.

“As we said after the season, we strongly believe in Tom,” president John Mara said. “We believe in the job he has done, and we believe in his ability to lead our team in the future. Everybody was on the same page in arriving at the extension.”

Coughlin, who will be 65 next month, faced speculation at the end of last season about his job security. Even though the Giants won the Super Bowl in 2008, the team has failed to make the postseason the last two seasons. The team made it clear at the end of last season that he'd return.

“As I was when I was hired in 2004, I am grateful for the opportunity,” Coughlin said. “To be the head coach of the New York Giants is the fulfillment of a dream for somebody who grew up where I grew up and when I grew up. As I have said roughly a thousand times, we’re all on one-year contracts in this business, but the reality is that I am thankful to work for people like the Maras and the Tisches and with people like (General Manager) Jerry Reese and his staff, as well as my coaching staff and our players.”

Coughlin was hired in 2004 and has only had one losing season with the team. He has a 65-47 career record with the team with two NFC East titles.
